Abstract
A series of novel ternary organic-inorganic mesoporous polymeric hybrids TTFA-S16-Eu-PMMA, TTFA-S16-Eu-PMAA, and TTFA-S16-Eu-PVP (TTFA = 2-Thenoyltrifluoroacetone; PMMA = polymethyl methacrylate; PMAA = polymethacrylic acid; PVP = polyvinylpyrrolidone) have been assembled by the Eu(3+) complex covalently attaching to the TTFA directly functionalized ordered mesoporous SBA-16 and organic polymer. FTIR, UV, XRD, TEM, N(2) adsorption measurements, photoluminescent spectra, and TG plots were characterized, and the results reveal that they all have high surface area, uniformity in the mesostructure, and good crystallinity. In addition, the ternary rare earth mesoporous polymeric hybrids show an overall increase in luminescent lifetime and quantum efficiency compared to binary rare earth mesoporous hybrid TTFA-S16-Eu, especially the mesoporous hybrid with PVP exhibits the highest luminescence quantum efficiency and longest lifetime.
